Title: Sample applicator unit - with absorption openings in application elements separable by interference fit holders
Inventor: WATANABE SADAHIRO
IPC: G01N27/447
Filed: 1990-04-11
Abstract: A sample applicator for use in a cataphoretic analysis of serum protein has a row of seperable applicator elements, each with an opening to absorb a sample. One of these individual elements is divided in turn from the rest, held and carried away. A row (12) of separable applicator elements (12a) have an opening (15) for the absorption of a blood serum sample. A number of holders (20) in a case out of many equal to the number of rows) can be lowered to sever each element along the dotted line (13). The lead-in chamber facilitates the engagement of the two with a slight press fit.

Inventor: SEZI TEVFIK DR
IPC: G06F3/05
Filed: 1991-05-03
Abstract: The invention concerns a circuit arrangement for converting a plurality of analog electrical measurement signals to corresponding digital signals. To obtain such a circuit with a fairly simple structure, antialiasing filters (11) on the input side are connected on the output side to at least two multiplexers (14, 20; 26, 27) associated with at least two scanning-holding circuits (15, 21; 28, 29). At least two analog-digital converters (16, 22; 30, 31) are connected on the input side to the output of a scanning-holding circuit (15, 21; 28, 29). An evaluation device (18) is arranged after the at least two analog-digital converters (16, 22; 30, 31) and determines, in an evaluation interval (O - T1), several digital values corresponding to scanning values of an electric signal (M1, M2) and averages them to produce the corresponding digital signal. The at least two multiplexers (14, 20, 26, 27) are connected to a control device (24) which controls said multiplexers so that the outputs of the antialiasing filters (11) are connected consecutively and in sequence via one multiplexer (e.g., 14) and, at the same time, consecutively and in reversed sequence via the second multiplexer (e.g., 20) to the scanning holding circuit (e.g., 15, 21).

Abstract: An outer ring for a vibration-proof homokinetic joint has an inner casing (14) and an outer casing (13). Vibration-proof members (23) made of an elastic material are disposed between the inner and outer casings. The outer casing (13) is formed on an inner peripheral surface with protrusions (16) spaced circumferentially. The inner casing (14) is formed on an outer peripheral surface with grooves (20) spaced circumferentially to receive the protrusions (16). Thin plate members (22) are mounted between adjacent protrusions (16) and are bonded to the vibration-proof members (23). The vibration-proof members are bonded to the outer surface of the inner casing (14) and thus displacement of the inner casing (14) relative to the outer casing causes deformation of the vibration-proof member which is limited by abutment of the side walls of the grooves (20) with the protrusions (16). In another embodiment the vibration-proof members are bonded directly to the inner wall of the outer casing (13) rather than to the thin plate members. <IMAGE>
